When two persons are talking to one othere, they know the context to talk within where they are hainvg conversesion.
If one person is talking to self and saying 30 and 5... 4 ok that's good, but the person sitting next to that person, don't know the context, and confused how 30 and 5 could be 4, it should be 35. But the first person is adding 5 to 30th December, this is 4 January.
